Abstract : DISE (Discrimination and Identification of Seismic Events) is an interactive computer program with graphics support and currently runs on a VAX-11/780 computer at the SDAC. Using various commands which are available, the seismic analyst may employ location data or waveform measurements to identify unknown events. Groups of epicenters may be formed, and a lower level of subgroups is formed when particular stations or variables are selected for discrimination purposes. The program supports two basic approaches to event identification using waveform-derived data: multivariate discriminant functions of multivariate clustering. (Author)
